Abstract: A method for synchronizing clocks in a distributed computing system in the presence of faults. The condition to be renewed guarantees that all clocks of correct processors never deviate by more than some maximum amount. This condition is achieved by periodically resynchronizing the clocks so that the correct clocks do not deviate by more than some minimum deviation. In the process of resynchronization, a correct clock is never adjusted by more than a maximum amount during a period and it is never set back. The method requires ascertaining whether a valid time value message has been received within a specified period. A message is valid if it was received within an inverval predetermined as a function of the number of signatures from other processors appending the message. If the valid message has not been received within the current period, then the local processor originates and broadcasts to all processors exactly one time value message and appends thereto its unforgeable signature. On the other hand if a valid message has been received, then the local processor appends its unforgeable signature to the message and passes exactly the one message on by broadcasting to all processors. As part of the protocol involving broadcasting of a message, each processor resets the time for expected resynchronization and updates its local clock.

Abstract: Zur Verbesserung der dynamischen Eigenschaften von Halbleiterbauelementen, die nur in einer Polarität hohe Sperrspannungen aufnehmen müssen (Dioden, rückwärtsleitende Thyristoren und asymmetrische Thyristoren), werden vielfach Struckturen mit einer aus zwei Schichten bestehenden n-Basis angewendet. Bei einem Halbleiterbauelement mit mindestens einer pn<->n-Schichtenfolge wird zur Verbesserung der Sperrfähigkeit vorgeschlagen, die Dicke (S) und die Dotierung einer n-Stoppschicht (4) derart zu wählen, dass gilt: <IMAGE> mit e = Elementarladfung, ε = Dielektrizitätskonstante des Halbleiters, ND = Donatorenkonzentration, x = Wegkoordinate, 0.8 <=k <= 1,0 und En = Feldstärke am n<->n-Uebergang. Dadurch wird erreicht, dass die geometrischen Bedingungen der Randanschrägung weniger stringent sind. Der Rand kann auch mit üblichen Aetzprozessen geformt werden.

IPC: C08F6/12

Abstract: A separation process has been found in which a polymer-solvent solution separates into phases of highly different composition which are in equilibrium over a broad temperature range. Upon addition of the phase separating agent, which is near or above its supercritical conditions, rapid disengagement into two phases occurs. The relative volume of solvent rich phase is substantially larger than the polymer rich phase. The process can be practiced at relatively low temperatures such as those employed in polymerization or post-polymerization processes. The separation is accomplished by adding or elevating the concentration of a phase separation agent to or above a minimum effective concentration, which causes the UCST and LCST lines to merge. Suitable phase separating agents are organic and inorganic compounds that are gases at 1 atm pressure and 25°C. Due to the gaseous nature of the phase separating agent, it is easily removed from the solvent phase for reuse in the process.

Abstract: Sporozoites of coccidia fail to develop in chickens which are immune and many are blocked from penetrating host cells. Although previous attempts to immunize chickens with non-viable coccidial antigens have been unsuccessful it has been discovered that extracts from sporozoites or sporulated oocysts of E. tenella induce high levels of protective immunity. These extracts contain at least 15 polypeptides many of which are associated with the surface of the sporozoite and induce good immune responses. Antibody to these polypeptides blocks sporozoite-host cell penetration in vitro and neutralizes sporozoites in vivo. One or more of these polypeptides may be used as an antigen to protect against coccidiosis.

Abstract: A process for producing at the same time degummed vegetable oils and gums of high phosphatidic acid content is described. The starting materials for this process are vegetable oils which have been conventionally water degummed and accordingly still contain too much non-hydratable phosphatides and iron for further processing by physical refining and providing a refined oil of good keepability. Therefore in a first stage of the disclosed process a non-toxic aqueous acid, e.g. phosphoric acid, is finely dispersed in the water degummed oil and sufficient contact time is allowed to complete the decomposition of the metal salts of phosphatidic acid. In a second stage a base is added to increase the pH above 2.5 without substantial formation of soap and in a third stage the aqueous phase containing the gums and the oil phase are separated. Surprisingly this process not only results in a degummed oil with very low phosphorus and iron contents which make the oil suitable for physical refining but also provides gums of high phosphatidic acid content with improved usability.
